Well, that depends, is this a true 6.74?...Thats like hearing about the kid that throws 90 but then when he is actually gunned its more like 84 - 85, or the catcher pop time of 1.8 when in reality it is closer to a 2.0.
Check out
Perfect Gamewebsite, and see what the Showcase 60 times are. A 6.7 would get you to the front of the pack at any age. Especially as a 15 year old. I personally seen a "burner" a few years ago from Nevada, his name escapes me right now, but he ran a 6.4 - 6.5.....
